在spring5.3之后，使用

        corsConfiguration.addAllowedOrigin("*");

会抛出异常 

java.lang.IllegalArgumentException: When allowCredentials is true, allowedOrigins cannot contain the special value "*" since that cannot be set on the "Access-Control-Allow-Origin" response header. To allow credentials to a set of origins, list them explicitly or consider using "allowedOriginPatterns" instead.

引起在5.3之后，引入了

corsConfiguration.addAllowedOriginPattern("*")

所以请替换使用
